W3C - Leading the Web to its Full Potential
Presented by: Jean-François Abramatic, 11:00 - 11:30
W3C Chairman Jean-François Abramatic will highlight W3C's mission and unique role within the Web community. Created in 1994 by the Laboratory for Computer Science at the Massachusetts Institute of Technology, W3C invited the National Institute for Research in Computer Science and Control (INRIA-France) in April, 1995 to become the European host of W3C. In August, 1996, the Shonan Fujisawa Campus of Keio University became the W3C host site covering Asia. W3C gathers more than 250 organizations from 25 countries, and the W3C members themselves belong to a large variety of organizations, including: software and hardware companies, communication and content providers, large end-user companies, research laboratories and universities. W3C receives support from those government organizations which believe that the Web will provide the infrastructure of the Global Information society. Recent achievements as well as future plans will be presented highlighting the original design approach developed at W3C.

W3C Architecture Domain
Presented by: Dan Connolly, 11:30 - 11:50
The W3C Architecture Domain seeks to improve the functionality of the Web via several key technologies that form the basis for much W3C activity. This includes Extensible Markup Language (XML), the next generation of HTTP (HTTP-NG), Synchronized Multimedia Integration Language (SMIL) and the newest version of Jigsaw, W3C's testbed Web server written in Java.

HTTP - NG: Web Characterization
Presented by: Jim Pitkow, Xerox PARC, 11:50 - 12:30
To successfully design and implement the next generation of the HTTP protocol, it is essential to understand the characteristics of the Web and how the Web is being used. This is true for any complex system, but too often it has been neglected in the evolution of the current Web. The Web Characterization Group (WCG) group is bringing together specialists from the academic world as well as from the commercial world to build a knowledge base of known Web characteristics, designing mechanisms to extend our views into the near future. The WCG group is characterizing the kinds of tasks performed and the kinds of documents retrieved using HTTP. The task of the group is to produce a snapshot of how the Web is currently used, as well as to build a framework for periodic resampling of the Web.

HTTP - NG: Protocol Design
Presented by: Henrik Frystyk Nielsen, 2:30 - 3:10
The goal of the HTTP-NG Protocol Design Group is to test the hypothesis that the current HTTP/1.X approach to Web protocol design can be replaced with a more useful design approach. The design approach is one in which the Web is expressed as a particular set of interfaces that are on top of a generic distributed object system designed with Internet constraints in mind. The benefits that a modularized, layered design provide are fundamental for the Web's continued prosperity. These benefits also allow easier evolution of the protocol standard, the interface technology that facilitates Web automation, easier application building, and so on. We intend to do other pressing HTTP work, notably, further performance improvements in the context of HTTP-NG. To demonstrate the feasibility of the new design, the Protocol Design Group is working toward implementing a testbed based on experiences gained in the Web Characterization Group.

Extensible Markup Language (XML)
Presented by: Dan Connolly, 4:00 - 4:45
In the immediate past, users who wanted an HTML feature or tag that was not in the HTML version had to wait for the next HTML release or the next browser release. But with Extensible Markup Language (XML), the evolution of data formatting is decentralized. With XML's extensibility, users can add features simply by creating tags that cater to vertical markets. One of the key target applications for XML will be in metadata, which is based on Resource Description Framework (RDF). Using RDF, users will be able to meet the requirements of large-scale Web content providers for industry-specific markup,vendor-neutral data exchange, media-independent publishing, one-on-one marketing, workflow management in collaborative authoring environments and intelligent-client processing of Web documents.

Developments and Extensions in Jigsaw
Presented by: Daniel Veillard and Yves Lafon, 4:45 - 5:20
We will present Jigsaw's latest development and give a tour of Jigsaw's key applications and testbeds. Jigsaw, W3C's own Web server, is a generic framework for building Internet servers written in Java. It provides a sample implementation of HTTP/1.1, and is designed with extensibility in mind. As a result, Jigsaw has been used inside and outside of W3Cto build advanced HTTP clients and servers. Latest developments in Jigsaw are highlighted in the following key applications and testbeds: Jigedit, W3C's front-end to Web authoring with versioning support; Amaya-Java, an extension of Amaya using Jigsaw HTTP client classes; PICS label bureau: extensions to serve PICS ratings; ICP multicast: building large Web caches using a cluster of Jigsaw servers; HTTP-NG testbed: taking advantage of the new features in Jigsaw 2.0.

Synchronized Multimedia Integration Language (SMIL)
Presented by: Dick Bulterman, CWI; Mark Hakkinen, Productivity Works; and George Kerscher, Daisy Consortium, 5:20 - 6:00
In this session, this latest addition to W3C's set of powerful Web languages will be shown for the first time ever at a Web conference. In the last year, W3C has developed the Synchronized Multimedia Integration Language (SMIL), an XML-based language that enables multimedia to be presented on the Web. SMIL allows writing interactive education and training material for the Web and, more generally, "TV-like" content which includes synchronized audio and video streaming.The three presenters will highlight the features of SMIL and also give a sneak preview of the very first SMIL implementations.

Day 2 -- Thursday, April 16

User Interface Domain Overview
Presented by: Vincent Quint, 11:00 - 11:20
The User Interface Domain gathers W3C's activities related to user and/or computer communications on the Web. In particular, the User Interface Domain is working on formats and languages that will present information to users with greater accuracy and with a higher level of control. Current activities include HTML, Style Sheets, Document Object Model, Math, Graphics, Fonts, Internationalization and the development of Amaya, a sound technology base on which to experiment.

The Future of HTML
Presented by: Dave Raggett and Tatsuya Hagino, 11:20 - 12:00
Many new ways for browsing the Web are now appearing and include: car-based computers, handheld computers and palmtop computers, cellular phones, regular phones (voice browsers) as well as Web TV. The global reach of the Web also makes it imperative to master internationalization. This talk will explain how to exploit the W3C HTML 4.0 Recommendation to make user's documents accessible on all browsers and to all people, as well as explaining ongoing work at the W3C on mobile access and speech. In addition, we will present the brand new W3C specification for the Mathematical Markup Language (MathML) and its application to including mathematical expressions in Web pages.

Internationalization (I18N)
Presented by: Bert Bos and Martin Dürst, 12:00 - 12:30
This session will focus on the basic needs and principles of Internationalization, as well as the latest developments in Internationalization. To ensure that the World Wide Web is truly world-wide, the W3C has put much effort into the Internationalization of its specifications, in particular HTML 4.0, XML 1.0, and Cascading Style Sheets, level 2 (CSS2). Recently, this effort has been strengthened by creating the Internationalization Working Group and the Internationalization Interest Group, which are chartered to review the specifications that other working groups produce, and to design guidelines for Internationalization on the Web.

Cascading Style Sheets, eXtensible Style Language, Fonts, and Graphics
Presented by: Håkon Lie and Chris Lilley, 2:30 - 3:30
This session will present the latest advances in Cascading Style Sheets, level 2 (CSS2), XSL (Extensible Style Language), and Fonts and Graphics.CSS2 is a style sheet language that allows authors and users to attach style such as fonts, spacing and aural cues to structured documents, such as HTML and XML. The CSS2 language is widely implemented, human-readable and writable, and expresses style in common desktop publishing terminology. Both CSS2 and the new XSL use a common formatting model, as do other specifications that specify presentation in any way, such as MathML, SMIL and HTML 4.0. Work also is starting on a scalable vector graphics language, written in XML, which can be controlled by style sheets.

Document Object Model (DOM)
Presented by: Lauren Wood, SoftQuad, 4:00 - 4:30
This session will give an overview of the Document Object Model, and where it fits into W3C activities. Relevant relationships to other groups will be given, as well as a description of where the group currently is in relation to its goals. The W3C DOM Activity is aimed toward designing an interface to an XML or HTML document that also allows application of a CSS style sheet. The interface is defined in a platform- and language-neutral way. We envisage script authors and programmers being able to use the interface to manipulate Web pages by changing the content, structure and style of the page.

Amaya - A Complete Web Authoring and Browsing Environment
Presented by: Irène Vatton, 4:30 - 4:50
Amaya is W3C's own client software, used to demonstrate and test many of the new developments in Web protocols and data formats, such as HTTP, HTML, CSS, PNG, XML, MathML, scalable vector graphics, PICS and more. Amaya is a versatile and extensible tool in that new features can easily be added, and it is available on both Unix and Windows '95/NT platforms. It is a complete Web authoring and browsing environment that focuses on document structure with a WYSIWYG-style interface.

W3C Web Accessibility Initiative (WAI)
Presented by: Judy Brewer and Daniel Dardailler, 4:50 - 6:00
WAI International Program Office Director Judy Brewer and WAI Technical Activity Lead Daniel Dardailler will provide an overview of progress in the Web Accessibility Initiative from the perspective of the business benefits of addressing accessibility in the design of Web-based content and applications. This overview will include the WAI Technical Activity, which encompasses technology, guidelines, and tools work, as well as the WAI International Program Office, which encompasses education and outreach, and research and development. Highlights will include the WAI Accessibility Guidelines: Page Authoring specification and upcoming working drafts of accessibility guidelines for user agents and authoring tools, as well as accessibility improvements in HTML 4.0, Cascading Style Sheets, level 2 (CSS2), and Synchronized Multimedia Integration Language (SMIL). In the area of WAI education and outreach, the presentation will cover WAI educational materials on accessibility which will be available in the coming months.

Day 3 -- Friday, April 17

W3C Technology & Society Domain
Presented by: Alan Kotok, 11:00 - 11:15
The W3C Technology & Society Domain focuses on society's ethical and legal issues as they arise from applications of Web technology. Acting Domain Leader Alan Kotok discusses the key mission that W3C has as it seeks to understand these issues, in part by changing the technology, and in part by educating users about the technology's benefits, costs, and limits. The current W3C focus is on continuing to establish trust on the Web, which it achieves by selecting the following specific activity areas: The W3C Metadata Activity, which provides a mechanism for creating machine-readable statements so that statements can have agreed-upon meanings; the W3C Digital Signature Initiative, which provides a mechanism so that signed metadata can securely authenticate who is making these machine-readable statements. The PICS activity addresses filtering content on the Web. The recently released W3C PICSRules specification enables filtering rules to be created so that they are machine-understandable and exchanged among users.

Resource Description Framework (RDF)
Presented by: Josef Dietl, 11:15 - 11:45
This presentation will provide an overview of the capabilities of RDF, including some examples of how it will be used for publishing metadata on the Web. The presentation is directed at developers interested in building tools to automate Web tasks, as well as authors wishing to add metadata markup to their documents, and architects planning to use XML to define characteristics of other Web resources. Metadata is data about data. In the Web context, metadata is data that describes Web resources. The goal of the W3C Metadata activity is to add machine-understandable metadata to the Web. The Resource Description Framework (RDF) provides the infrastructure for this Web metadata. Examples of applications include sitemaps, content ratings, stream channel definitions, search-engine data collection (web crawling), digital library collections, and distributed authoring. RDF allows different application communities to define the metadata property set that best serves the needs of each community. In addition, RDF will provide a uniform and interoperable means to exchange metadata between programs and across the Web. Furthermore, RDF will provide a means for publishing both a human-readable and a machine-understandable definition of the property set itself.

Platform for Privacy Preferences (P3P)
Presented by: Lorrie Faith Cranor, AT&T, 11:45 - 12:15
In this session, Lorrie Faith Cranor will discuss some of the motivations for P3P, and will present a progress report on the P3P project to date.The Platform for Privacy Preferences (P3P) project is intended to allow Web sites to express their privacy practices, and for users to exercise their preferences over those practices. If a relationship is developed, subsequent interactions and any resulting data exchanges are governed by an agreement between the site and the user. After configuring privacy preferences, individuals should be able to seamlessly browse the Internet; their browsing software negotiates with Web sites and provides access to sites only when a mutually acceptable agreement can be reached. P3P efforts focus on how to exchange privacy statements in a flexible and seamless manner.

Electronic Commerce
Presented by: Josef Dietl, 12:15 - 12:30
An important factor in leading the growth of the Web is electronic commerce: the ability to buy, sell, and advertise goods and services to consumers. The Web is a new communications medium and, like all new media, it requires us to rethink existing solutions to age-old problems. The Web also enables a new class of commodity in which it becomes both useful and practical to have units of payment much smaller than the older collections systems were capable of handling. This presentation will discuss new W3C initiatives in micro-payments and consumer-to-business data exchange, including how pricing and payment system markup might be embedded within Web pages.

W3C Town Hall Session
Presented by the W3C Executive Management, 2:30 - 3:30
Following the positive response at last year's WWW6 Conference, the W3C Track will close with a "Town Hall" session with W3C's management team, allowing the community to offer feedback on the Consortium's direction and representation.
